DescriptionRFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 Sprocket

Product details :

Features

Manufacturer Ref: FXRS 61-50 ALRD

The RFX Pro Series Armalite 520 sprocket combines lightweight design and durability tailored for motocross. Developed and tested by racing teams, it features a CNC-machined 7075-T6 aluminum core and a high-carbon steel (HCS) outer ring to preserve tooth lifespan while minimizing unsprung weight.

Type: Armalite composite double sprocket (steel/aluminum)
Number of teeth: 50
Chain pitch: 520
Color: Anodized red
Feature: Hexagonal interface between inner and outer ring to optimize power transfer and reduce stress on the rivets
Design: Lightweight CAD profile, mud clearance grooves to limit wear, and rigid anti-twist construction

Easy installation on standard hubs: the sprocket aligns with existing holes and is secured with the provided bolts (use medium thread-locking compound and adhere to the manufacturer's torque specifications). Ideal for motocross riders seeking a durable, high-performance, and racing-styled component.

Compatible motorcycles (examples): Beta RR 430 4T Racing 2023, Beta RR 430 4T 2023, Beta RR 390 4T Racing 2023.
